SPECIFICATION forming part of Letters'Patent No. 786,974, dated April11, 1905. Application filed June 20, 1904. flerial No. 213,437.

To all whom, it may concern:

Be it known that I, FLORENTINE KREGGZY, a subject of the Czar of Russia,and a resident of Lodz, in Russian Poland, have invented a certain newand useful Improved Protecting and Ventilating Cover for Vessels, ofwhich the following is a specification.

This invention relates to improvements in lids or covers for vesselsadapted to contain edible substances or articles of nourishment and thelike; and its object is to completely prevent the entrance of dust intosuch vessels, but at the same time to allow of free access of air to theinterior thereof, so that the presence in the vessels of fresh aircompletely free from particles of dust will prevent the decomposition ofthe contents of the vessels,-

inder 4 has an external-domed flange 5, adapt ed to rest on the rim ofthe vessel to be covered. The upper end of the cylinder 1 is closed andis provided with the handle 6. The

projecting edge 2 serves to protect the outer surfacev of the cylinder 1from moisture such as is, for instance, in damp cellars liable toaccumulate in drops and might reach the gauze 3 and penetrate into theinterior of the vessel. The interior cylinder 4 protects the gauze frommoisture which might be splashed against the said part 3 when the vesselis set down on a wet floor or over moist goods.

The cover can be made of enameled or unenameled metal, china, or othersuitablematerial.

I declare that what I claim is A protecting and ventilating cover forvessels comprising in combination a vertical open cylinder with anoutwardly-extending flange at the base thereof, a larger cylinder havingits axis concentric with, the former and closed above by a flat disk, anannular finely-perforated portion extending across the spaceintermediate of the cylinders from the upper edge of the inner cylinderto the lower edge of the outercylinder and an outwardly-projectingdownwardly-curved flange about the outer cylinder ata distance abovethe'lower edge thereof.

In testimony whereof I aflix my signature in presence of two-witnesses.

' FLORENTINE KREGCZY.
